the casing sectionsupon the fly wheel and v To all whom it may concern:

Be it known that I, ARTHUR C. HALL, .a citizen of the United States,residing at Fulton, in the county of Oswego and State of New York, haveinvented certain new and useful Improvements in Engines, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

This invention relates to engines'and has for its primary object toprovide means for utilizing the exhaust of the engine as an auxiliarydriving medium whereby a combination reciprocating and rotary engine isproduced and a maximum of power thus obtained from a minimum fuelconsumption.

A further object of the invention resides in the provision of improvedmeans for directing the exhaust from the engine cylinders against aplurality of cupped'blades arranged in the periphery of'the fly orbalance wheel of the engine.

Another and more specific object of the invention is to provide asectional peripheral band or casingwhich is so mounted upon theperiphery of the fly wheel that the fullimpact force of the exhaustgases will be expended against the blades mounted in the.

wheel, thereby giving an additional rotary impulse to the engine shaftand materially increasing the Working energy of the engine.

A still further object of the invention is to provide a device of theabove character which is simple in construction, strong, du-

rable and eflicient inpractical use and'may be manufactured and appliedto the ordinary type of reciprocating engine at a minimum expense.

With the above and other objects in view as will become apparent as thedescription proceeds, the invention consists in certain constructions,combinations and arrangements of the parts, .that I shall hereinafter,

fully describe and claim..

For a full understanding of the invention, reference is to be'had to thefollowing de-. scription and accompanying drawings, in

Figure 1 is a side elevation of anengine showing my improvements appliedthereto; Fig. 2 is an enlarged vertical section through the rim of theflywheel and the sectional peripheral band or casing arranged thereon;Fig. 3 is a section taken on the line 3-3 of Fig. 2. Fig. 4: is a detailtransverse 6 section illustrating the manner of mounting applying alubricant to said wheel.

In reciprocating engines of the single or inultiple cylinder type usingeither gas or steam as the actuating fluid, the larger part of the fluidpressure is expended in moving the reciprocating pistons and in gasengines, the heat of the exploded gases is greatly reduced by the waterjacket of the piston cylinder. Much of the power of the actuating fluidis also exhausted to the atmosphere. As above outlined, the purpose ofthe present invention is to provide means for utilizing this wastedenergy and transmitting the same to the engine shaft, so as tomaterially inc'reasethe working power of the engine without increasingthe consumption of fuel.

For convenience in illustration, I have shown the invention applied toan engine of the horizontal single cylinder type, but it will beunderstood that the invention is also applicable to double or multiplecylinder engines of either the horizontal orvertical type and also tosteam or gas engines irrespective of their particular construction.

' With the above end in view I have illustrated one embodiment of myinvention in the drawings, wherein 5 designates the engine cylinder and6 the exhaustport thereof, from whichthe exploded gasor steam isexhausted after the same has acted against the engine piston; To thisexhaust port one end of a pipe 7 is connected in any approved manner.The fly or balance wheel 8 is fixed upon the engine shaft 9. Theperiphery of this fly wheel is provided with a deep annular groove orchannel 10, the opposed walls of which are'rabbeted' as indicated at 11,to provide annular shoulders 12. In the shoulders 12 and in the base ofthe channel 10 the blades or vanes 13 are secured. These blades are bentor curved as clearly shown in Fig. 2, so that the full propulsive effortof the steam or gas in its' impact against these blades will beutilized. Upon the fly wheel a band or casing is arranged. This casingconsists of two substantiall semi-circular sections 14, the extremities0 which are laterally flanged and apertured to receive the connectingbolts 15. The outer surfaces of these casing sections are preferablyconvex as shown to give a finished appearance to the fly wheel. Theupper casing section is centrally provided with a port 16 to which oneend of the pipe 7 leading from the exhaust 4 wheel to a minimum.

' the inner end of into which t of the engine is connected. These casingsections loosely en gle upon the spaced annular shoulders 12 0 t e ywheel and suitable 011 cups ,17 are mounted in the upper section 14to'supply oil to these shoulders and thus reduce friction between thecasing and fly The lower casing section 14 is centrally provided with aport 18 which communicates with radually' deepening pocket 19 e gasesare discharged from the blades 13 on the-fly wheel. To the port 18, adischarge or exhaust pipe 20 is conn-ected. lVhile the pipes 7 and 20may be relied uponto maintain the sectional casing sections 14 ina'stat-ionary position with relation to t-hefly wheel, I preferablyprovide the obliquely disposed braces 21 which are secured to the casingsections adjacent one of their ends and to the respective intake andexhaustpipes. It will of course be understood that If necessary,additional bracing means may be provided for the sectional casing. v I

From the foregoing it is believed that the construction, operation andseveral advantages of the invention will be clearly understood. I

It will be apparent that the device not only provides eflicient meansfor greatly inthe end of a creasing the operating efiiciency of theengine but also serves as a muffler for the exaust from the enginecylinder. The exhaust gases acting against the blades 13 on the .fiywheel serve as an auxiliary driving medium for the engine shaft so thatthe engine may be operated at greatly increased speed over the ordinarytype of reciprocating engine without my device applied thereto, while atthe same time the consumption of fuel and consequent operating cost isnot increased. Furthermore, it will be apparent that the invention isapplicable to all types of reciprocating engines without necessitatingany change in the form or arrangement of the working parts thereof. Thedevice maythus be readily'applied in its proper operative position uponthe engine at com-v paratively small cost.

-While I have shown and described the I preferred construction andarrangement of' the several elements, it will be obvious that theinvention is susceptible of considerable modification without de artingfrom the essential features or sacrificing any of the advantagesthereof.

Having thus described the invention, what is claimed is:

1. The combination with an engine, of a fly wheel for said engine havingan annular channel in its periphery and an annular shoulder at each sideof the-channel, spaced blades fixed in the walls of said channel, atwo-part casing arranged upon the periphery of the fly wheel and looselyengaged upon said annular shoulders, a pipe leadlng from the exhaust ofthe engine cylinder and connected to said casing to direct the exhaustedactuating fluid against the blades on said fly wheel, a discharge pipeconnected to to the atmosphere, and brace bars connecting the casingsections to the intake and dis charge pipes.

2. The combination with an engine, of a fly wheel for said engine.provided with a deep annular channel in its periphery and annularshoulders at each side of said channel, a two-part casing arranged uponthe periphery of the fly wheel and loosely contact-ing with saidshoulders, a plurality of spaced blades fixed in the walls of saidchannel, a pipe connected to the exhaust of the engine cylinder and toone of the casing sections to direct the exhausted gases from the enginecylinder against the blades of said fly wheel, the other of said casingsections being provided with an outlet port, a discharge pipe connectedthereto, the inner wall of said casing section being provided with agradually deepening pocket to direct the gases from the blades of thefly wheel into the discharge pipe, and obliquely disposed brace barsconnecting the respective casing sections to the intake and dischargepipes.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses.
